portCfg 2 Optional arguments for fciptunnel create and modify include: -n remote_wwn Specifies the remote-side FC entity WWN. -d description Specifies a descriptor for the FCIP tunnel, for example, "Tunnel 0 to San Jose Office". -c 0|1 Disables (0) or enables (1) compression on the specified tunnel. By default, compression is disabled. -f 0|1 Disables (0) or enables (1) FastWrite on the specified tunnel. By default, FastWrite is disabled. -t 0|1 -k timeout Disables (0) or enables (1) read/write Tape Pipelining on the existing tunnel (requires FastWrite to be enabled). Specifies the keep alive timeout, in seconds. Timeout values are 8 to 7,200. The default is 10. If Tape Piplelining is enabled, the minimum supported value is 80. -M 0|1 Enables (0) or disables (1) default VC QoS mapping on the specified tunnel. By default VC QoS mapping is disabled. There are two ways of prioritizing network traffic over FCIP tunnels: Differentiated Services (DSCP) and Layer 2 Class of Service (L2CoS). If the -M option is set, the VC on the FCIP outbound frame is mapped to both a DSCP and L2CoS value. These default values can be modified on a per-FCIP tunnel basis with the fciptunnel qosmap option. The -M option can be turned on or off any time. QoS map settings are unaffected by the -M option. -q control-dscp Specifies the DSCP (DiffServ Code Point) marking used for the TCP connection of the FCIP tunnel. This operand is optional. The range is 0 63. The default value is 0. -Q data-dscp Specifies the DSCP (DiffServ Code Point) marking used for the data TCP connection of the FCIP tunnel. This operand is optional. The range is 0 63. The default value is 0. -m time Specifies the minimum retransmit time, in milliseconds. The range is 20ms to 5000ms; the default value is 100ms. -r retransmission Specifies the maximum retransmissions. Values are 1 - 16. The default value is 8. If Tape Piplelining is enabled, the default value is calculated based on the minimum retransmit time to ensure that the TCP connection does not time out before the host times out. The specified value must be greater than the calculated value. -s 0|1 Disables (0) or enables (1) selective acknowledgement code (SACK) on the specified tunnel. -t 0|1 -v vlan_id Disables (0) or enables (1) read/write Tape Piplelining on the specified tunnel (requires Fastwrite to be enabled). Creates an FCIP tunnel with VLAN Tagging and Class of Service (CoS). Specify a vlan_id in the range between 1 and 4094. There is no default. If any other VLAN option is specified, the VLAN ID must also be specified. The following operands are optional with VLAN tagging: Fabric OS Command Reference 589 53-1001337-01
